U.S. Drug Enforcement Administration officials on Wednesday announced the results of the "largest-ever" synthetic drug takedown, a bust that included suspects in 35 states and five countries. Agents working in conjunction with local law enforcement agencies served more than 150 arrest warrants, including 11 in Louisiana.

The Louisiana arrests were in Terrebonne Parish, according to Special Agent Roberto Bryan Jr., a spokesman for the DEA's New Orleans Division. Those arrests included an unidentified New Orleans man who was a suspected supplier. He taken into custody in Terrebonne Parish on Wednesday morning.

"We executed 10 search warrants, three at businesses and seven at residences," Bryan said. "We seized a large quantity of synthetic marijuana, $500,000 to $600,000 in cash and four vehicles."

No other information about the Terrebonne Parish arrests was available Wednesday evening. The local busts were part of Project Synergy, a "global takedown" that national DEA officials said began in December.

After seven months of investigation, agents simultaneously served 375 search warrants in 49 U.S. cities as well as in other countries including Australia, Barbados, Panama and Canada. Other federal law enforcement agencies that participated in the investigation include U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement's Homeland Security Investigations division, the FBI and the IRS.

"Shutting down businesses that traffic in these drugs and attacking their operations worldwide is a priority for DEA and our law enforcement partners," DEA Administrator Michele Leonhart said in a statement released Wednesday.

Synthetic drugs are lab-created designer narcotics often marketed as herbal incense, bath salts, jewelry cleaner or plant food. Local law enforcement agencies have often come across synthetic marijuana blends sold as "POW!," "Nola Diamond" and "K2" at convenience stores or smoke shops. The drug mimics the effects of actual marijuana but with more hazardous consequences.

Agents with Project Synergy uncovered a "massive flow" of drug-related proceeds heading to Middle Eastern countries, according to the DEA. "The case and the investigation led to money transfers going to the Middle East," Bryan said. "There are money laundering and racketeering charges involved."

Bryan said agents have, so far, found no ties to any terror organizations. But the cases are still under investigation.
